Disability Diseases and Medical Conditions

Not every medical condition automatically qualifies for Social Security disability benefits. To receive SSDI or SSI, your condition must meet the Social Security Administration’s (SSA) definition of disability — meaning it must significantly limit your ability to work and be expected to last at least 12 months (or result in death).

Our Disability Diseases and Conditions category explains how specific medical conditions are evaluated by the SSA, including:

  • Conditions listed in the SSA’s “Blue Book”
  • Physical disabilities such as back injuries, heart disease, cancer, and neurological disorders
  • Mental health conditions including depression, anxiety, PTSD, and bipolar disorder
  • Chronic illnesses like lupus, multiple sclerosis, and fibromyalgia
  • Headaches and migraine disorders
  • Vision and hearing impairments
  • Autoimmune diseases
  • Respiratory disorders
  • Long COVID and emerging conditions

Each article helps you understand:

  • What medical evidence is required
  • How the SSA evaluates severity
  • What documentation strengthens your claim
  • Why certain claims are denied
  • When a medical-vocational allowance may apply

Even if your condition is not specifically listed in the Blue Book, you may still qualify if your symptoms prevent you from performing substantial work.

Understanding how your specific diagnosis fits into SSA guidelines can significantly improve your chances of approval.
